DNA replication is a process that occurs when DNA in the cells copies itself. This helps ensure that each new cell has its own complete genome during cell division. Can genetic diseases be cured?

DNA replication occurs in the S phase of the cell cycle. DNA replication is the process where DNA copies itself. This happens so that old cells can make new cells.
